COUPLING-ROD F03 THE AXLES OF AUTOMOBILES.

Specification of Letters Patent.

Patented Dec. 10, 1907.

' To all whom it may concern:

Be it know that I, THEODORE RoMMEL, engineer, a citizen of the FrenchRepublic, and residing at Neuilly-sur-Seine, France, have invented aCoupling or Tension Rod for the Axles of Automobiles, of which thefollowing is a specification.

The present invention relates to an improvement in couplin or tensionrods for connecting the rear a e of an automobile to a fixed point ofthe frame and the purpose thereof is to absorb the strains due to shocksimparted to the wheels by inequalities in the road surface. ,In theabsence of said coupling rods the s rings of the vehicles alone minimizesaid s ocks and since said springs absorb vibration in the verticaldirection only they do not operate under the best conditions. Hithertoordinary rods or shafts were employed which did not fulfil the re quiredconditions.

The improvements'consist in applying a double spring to the aforesaidcoupling or tension rods, the invention being represented in the annexeddrawin in which Fi ire 1 is a sectional side e evation showt e improvedcoupling rod applied to a 1n vehicle, and Fig. 2 is a sectional detailview of said rod.

The coupling or tension rod comprises two members 1 and 1 connectedtogether by a screw coupling or union 2 which permits of adjusting theeffective length thereof. One end of the-rod is pivotally connected asat 3 to the bearing of the driving pinion or to any' other fixed pointof the vehlcle frame; and

the other end enters a box 4 attached to the wheel axle 5 of thevehicle.

The member 1 of the coupling rod carries an abutment or enlargement 6located within the box 4 and at each side of said abutment is placed ametallic helical spring 7 and 7*, one of which 7 bears against the endof the box and the other 7 against a plug 8 screwed into the oppositeend of said box. .It will be obvious that said s rings will tend toabsorb the horizontal shoclis imparted-to the vehicle axle duringtraveling. The plug serves at the same time for adjusting the tension ofthe sp'rin What claim as my invention and desire to secure by LettersPatent of the United States is 1. The combination with a vehicle frameand wheel axle of a coupling or tension rod adjustable as to length andhaving a nondisplaceable connectlon at one end to said frame, and aspring connection between the other end of said rod and the Wheel axleaforesaid substantially as described.

2. The combination with a vehicle frame and wheel axle of a coupling ortension rod adjustable as to length and positively connected at oneendto said frame, a box con nected to said axle into which the other endof the rod enters and a spring within said box adapted to act on saidrod substantially as described.

3. The and wheel axle of a coupling or tension rod adjustable as tolength andpositively connected at one end to said frame, a box connectedto said axle into which the other end of the rod enters, an abutment onsaid rod within the box, and springs adaptedto act against oppositesides of said abutment substantially as described.

4. The combination with a vehicle frame and wheel axle of a coupling ortension rod adjustable as to length and positively connected at one endto said frame, a box connected to said axle into which the other end ofthe rod enters, an abutment on said rod within the box, a screw pluginserted into the'free end of the boxand a spring located at each sideof the abutment, said spring bearing at one end against said abutmentand at the opposite end against the wall of the box and screw plugrespectively substantially asdescribed.

In Witness whereof I have signed this speclfication in the presence oftwo witnesses.
